This article compares the execution efficiency of JavaScript and Python from the perspectives of language design, runtime environment, and application scenarios, analyzes the root causes of performance differences, and provides targeted optimization solutions.1. Underlying differences in language features and execution speed1.1 Type system and compilation mechanismJavaScript: A dynamic weakly typed language that relies on the V8 engine's Just-in-Time (JIT) compilation. JIT converts high-frequency bytecodes into machine code through hot code optimization (such as hidden classes and inline caches), significantly improving the speed of computationally intensive tasks.Python: A dynamic and strongly typed language that uses the CPython interpreter to execute bytecode line by line by default. Type checking and the global interpreter lock (GIL) cause its single-threaded performance to be usually lower than JS, but JIT compilers such as PyPy can increase the speed by 3-5 times.1.2 Memory Management ModelJS: Based on the design of automatic garbage collection (GC) and memory stack separation, it is suitable for scenarios with high-frequency creation/destruction of objects (such as DOM operations). V8's generational GC strategy (new generation, old generation) reduces pause time.Python: A combination of reference counting and generational GC, but manual intervention is required to handle circular references (such as gc.collect()). The memory overhead is higher than JS when operating on a large number of objects.1.3 Concurrent Processing CapabilitiesJS: Non-blocking I/O model based on event loop, high concurrent network requests through async/await (such as Node.js handling 10K+ connections). Worker Threads supports CPU-intensive task offloading.Python: GIL limits the parallel efficiency of multithreading, but multiprocessing and asynchronous IO (asyncio) can alleviate this problem. For computationally intensive tasks, it is recommended to use C extensions (such as NumPy).2. Typical scenario performance comparison test2.1 Numerical calculation (40th term of Fibonacci sequence)JS (Node.js 21.0): ~1.2 seconds (recursion not optimized) → 0.8 seconds after tail recursion optimizationPython (CPython 3.12): about 18 seconds → optimized to 0.01 seconds using iterative methodConclusion: Python should avoid deep recursion and give priority to using built-in functions and mathematical libraries.2.2 File IO throughput test (1GB data reading and writing)JS: Streaming (createReadStream) takes 2.3 seconds, memory usage < 100MBPython: Buffered read with open took 3.1 seconds, memory peak 1.2GBOptimization suggestion: Python can use io.BufferedReader or asynchronous aiofiles module.2.3 HTTP request throughput (1000 API calls)JS (Promise.all): Asynchronous concurrent completion time 4.2 secondsPython (asyncio + aiohttp): 5.8 seconds (affected by GIL scheduling)Tool selection: Node.js is preferred for high-concurrency API aggregation scenarios.3. Advanced performance optimization solutions3.1 JavaScript acceleration strategyEngine Optimization:V8 parameter tuning (such as adjusting the memory limit --max-old-space-size=4096)Use WASM to process low-level operations such as images/encryption (such as FFmpeg.wasm)Code level optimization:Avoid modifying object shape (hidden class destruction) and give priority to using TypedArrayUse for loop instead of forEach (2-3 times faster in Chrome)3.2 Python performance improvement pathInterpreter replacement:PyPy: Speed up pure Python code by 3-20 times (compatibility is about 95%)Numba: JIT compilation decorator to speed up numerical calculations (@jit(nopython=True))C-ization of key codes:Cython is compiled as a C extension (type annotations can improve efficiency by 50 times)Calling C libraries (such as ctypes/cffi) or Rust modules (via PyO3)3.3 Hybrid Architecture DesignEdge computing: Node.js is used to handle high-concurrency requests, and Python is responsible for data analysis (PySpark)Microservice splitting: Deploy computing-intensive modules (such as ML reasoning) as gRPC services, and JS/Python calls them through RPC4. Trade-off between development efficiency and ecosystem4.1 Rapid PrototypingPython advantages: Rich scientific computing libraries (Pandas, SciPy) and AI frameworks (PyTorch) accelerate algorithm verification.JS advantages: Electron/Vue cross-platform development, Three.js web 3D rendering and other scene ecosystems are complete.4.2 Deployment and Operation CostsPython: Virtual environment dependency management is complex (conda/poetry), and the image size is usually >1GB.JS: The problem of node_modules dependency nesting is prominent, but it can be optimized by using npm sharding packaging and Tree Shaking.4.3 Team Skill ReserveFull-stack teams can give priority to using Node.js to unify the front-end and back-end languages and reduce context switching costs.The data science team recommends using Python as the core and adopting hybrid programming for performance bottleneck modules.5. Final selection adviceScenarios where JavaScript is preferred:Real-time web applications (chat, collaboration tools)High-concurrency API gateway and BFF layerIn-browser computing (Web Workers)Scenarios where Python is preferred:Data cleaning and statistical analysis (Pandas)Machine Learning Model Training (TensorFlow)Automation scripts and DevOps toolchainBy properly choosing languages and optimizing methods, developers can strike a balance between execution efficiency and development efficiency. For example, using Node.js to build a microservice interface layer, using Python+Cython to process backend data analysis, and combining IP2world proxy services to implement high-performance applications such as distributed crawlers.As a professional proxy IP service provider, IP2world provides a variety of high-quality proxy IP products, including dynamic residential proxy, static ISP proxy, exclusive data center proxy, S5 proxy and unlimited servers, suitable for a variety of application scenarios.

This article explains how to use socks proxy and curl tools together, analyzes the configuration process and common problems, and recommends IP2world's high-performance S5 proxy solution.1. The core concepts of socks proxy and curlSocks proxy is a network protocol that can forward user requests through an intermediary server, supports TCP/UDP connections, and is often used to break through network restrictions or hide real IP. It is divided into SOCKS4 (basic protocol) and SOCKS5 (supports authentication, IPv6 and other extended functions).curl is a command-line tool used to transfer data based on URL protocols (such as HTTP and FTP). It supports proxy configuration for flexible network request control.IP2world's S5 proxy is based on the SOCKS5 protocol, providing highly anonymous, low-latency proxy services that can seamlessly adapt to the network request requirements of tools such as curl.2. Why do we need a socks proxy to perform curl operations?2.1 Anonymized data collectionHide the real IP address through socks proxy to avoid the target website blocking crawlers or automated scripts;Combined with IP2world's dynamic residential IP pool, it can simulate user behavior in multiple regions and reduce the risk of anti-climbing.2.2 Test API interfaceUse proxy IPs from different regions to test the regional response strategy of the interface;Verify the service provider's access restrictions on specific IP segments (such as IP2world's static ISP proxy can provide fixed IP).2.3 Debugging Network IssuesUse proxy servers to detect whether there is interception or DNS pollution in the local network environment;Compare the request duration in direct connection mode and proxy mode, and optimize the network link.3. The complete process of configuring curl with socks proxy3.1 Basic command formatIn the curl command, specify the proxy server address and port through the --socks5 or --socks5-hostname parameter:curl --socks5 IP:PORT target URLIf the proxy requires authentication, add the username and password:curl --socks5 username:password@IP:PORT target URL3.2 High-level parameter configurationTimeout control: Set the proxy connection timeout (in seconds) via --connect-timeout;Request header masquerading: Use the -H parameter to customize the User-proxy and other header information to simulate browser behavior;HTTPS support: SOCKS5 proxy is compatible with HTTPS by default, without the need for additional certificate configuration.3.3 Automation script integrationCall the curl command line in Python, Node.js and other languages, or directly use the libcurl library to bind proxy parameters. IP2world provides an API interface that supports dynamic acquisition of proxy IP and injection of scripts.4. Common Problems and Optimization SuggestionsQ1: What should I do if curl prompts "SOCKS protocol does not support HTTP proxy"?Confirm whether the proxy type is SOCKS5 (HTTP proxy requires the --proxy parameter);Check whether the curl version is too old (it is recommended to upgrade to v7.21+).Q2: How to verify whether the socks proxy is effective?Run curl https://api.ipify.org and compare the returned IP with the proxy IP.Use the IP detection tool in the IP2world backend to monitor the proxy status in real time.Q3: How to optimize the slow proxy speed?Switch to a low-latency node (such as IP2world's exclusive data center proxy);Reduce the number of concurrent requests to avoid triggering the proxy server's rate limit policy;Enable connection multiplexing (curl's --keepalive parameter).5.

IP2world's proxy IP service can effectively solve the anti-crawling restrictions of the target website and improve the collection success rate.1.1 Comparison of basic HTTP request librariesHttpURLConnection: JDK native library supports basic requests, and connection pool and timeout mechanism need to be handled manuallyApache HttpClient: provides connection reuse and asynchronous IO features, and supports custom interceptor chainsOkHttp: A modern HTTP client with built-in SPDY/HTTP2 protocol, automatic retry and fuse mechanism1.2 HTML parsing tool selectionJsoup provides DOM selector syntax similar to jQuery, and XPath is suitable for parsing complex nested structures. For dynamically rendered pages, you need to combine Selenium WebDriver to drive the Headless browser to generate a complete DOM tree.1.3 Proxy IP Management SolutionThe polling strategy needs to dynamically adjust the IP pool according to the response time. For geolocation needs, IP2world's static ISP proxy can be used. The anomaly detection module should monitor the blocking features (such as 403 status code, verification code jump) and automatically trigger the proxy replacement.2. Implementation of anti-crawler technology2.1 Request header feature simulationRandomly generate a User-proxy pool to cover mainstream browser versions, and dynamically set the Accept-Language and Referer fields. Cookie management needs to implement persistent storage and session maintenance, and generate Canvas hash values through browser fingerprint simulation tools.2.2 Request frequency control strategyThe adaptive delay algorithm adjusts the collection interval according to the response time. Redis is required to implement global rate limiting in a distributed architecture. Traffic camouflage technology can insert random scrolling/clicking events to simulate real-person operations. During the data collection process, IP2world's dynamic residential proxy can be used to achieve dynamic switching of IP addresses.2.3 Verification code cracking solutionImage recognition uses Tesseract OCR + convolutional neural network correction, and the sliding verification code simulates human movement patterns through a trajectory generation algorithm. Token hijacking technology requires reverse analysis of the front-end encryption logic, and secondary verification bypass can be achieved by binding a mobile phone number.3. Dynamic page rendering processing3.1 Headless browser configuration optimizationThe ChromeDriver memory limit is set to 1GB to prevent crashes, and CSS/image loading is disabled to increase rendering speed. Pre-executed JavaScript scripts can bypass the front-end detection logic, and the browser fingerprint modification plug-in needs to update the feature library regularly.3.2 AJAX request interception technologyDevTools Protocol monitors Network events and dynamically injects Hook scripts to capture XHR requests. Interface reverse engineering requires parsing the Protobuf data format and requesting the signature algorithm to restore the encryption process through AST parsing.3.3 Data Stream Processing ArchitectureThe producer-consumer model is used to separate page acquisition and parsing logic, and the message queue buffers burst traffic. The distributed storage solution designs sharding rules, and Elasticsearch establishes full-text indexes to support fast retrieval.4. Enterprise-level crawler system design4.1 Task Scheduling MechanismThe priority queue handles urgent collection needs, and the failed task retry strategy uses an exponential backoff algorithm. Dependency management requires the construction of a DAG task graph, and scheduled tasks support Cron expression configuration.4.2 Monitoring and Alarm SystemPrometheus collects indicators such as QPS and success rate, and configures hierarchical notification strategies for threshold alarms. Link tracking records the complete life cycle of each request, and performance analysis flame graphs locate bottleneck modules.4.3 Compliance assuranceThe Robots.txt parsing module automatically complies with crawling rules, and data desensitization removes personal privacy information. The access log retention policy complies with GDPR requirements, and the evaluation report needs to be updated monthly.As a professional proxy IP service provider, IP2world provides a variety of high-quality proxy IP products, including dynamic residential proxy, static ISP proxy, exclusive data center proxy, S5 proxy and unlimited servers, suitable for a variety of application scenarios.
